To @ZZ whom, it may concern:

Be it known that I, THERON S. CARROLL, a citizen of the United States,residing in W insted, in the county of Litchfield and State ofConnecticut, have invented certain new and useful Improvements inWood-Sawing Machines, of which the following is a specification.

Thisinvention relates to machines for sawing wood, and has for oneobject a machine of the class specified embodying novel features andwhich is espcially adapted for sawing logs or other work on a taper, butwith a minimum'loss ofV stock, to produce, for instance, iiagstaffs,masts for vessels, dre., of proper form.

Other objects of my invention are to provide means whereby the machinemay be adjusted to stock of different sizes and also to provide meansfor adapting the machine for cutting objects of different tapers, as maybe required; and a further object is to provide an improved constructionof work-sustaining devices, as will be hereinafter described and asillustrated in the accompanying drawings, in which-#- Figure 1 is a planView ot' a machine constructed in' accordance with myinvent-ion. Fig. 2is a side View of the same. Fig. 3 is a top view of the head-stoclemployed in connection with the table and adapted for holding the logs,and Fig. 4 is a side viewthereof. Fig. 5 is a top view of the tail-stockcooperating with the head-stock, and Fig. 6 is a side view of the same.Fig. 7 is a transverse section of the table on line 7 7, Fig. 1, on anenlarged scale. Fig. 8 represents a plan view of a rest for sustainingthe log, and Fig. 9 is a partial front View of the table and rest.

Similar characters of reference designatel vided on the table T forsecurely holding the log during the sawing operation, such meansconsisting, substantially, of a head-stock H and a tail-stock I, theformer of which is preferablyadjustable at the right-hand end of thetable T, while the tail-stock may have considerable longitudinaladjustment adjacent the left-hand end of the table, as clearly shown inFig. 1. The table T is preferably formed of a framework consisting ofthe side pieces 1l and 12, joined at their ends and at intermediatepoints by ties 13 to form a rigid structure.

Located adjaceht to the head and tail stocks and also at a pointintermediate the same are rests R, upon which the log L may be placedand supported preparatory to its engagement with the centers or spindlescarried by the head and tail stocks. The construction of the rests R isclearly shown in Figs. 7 to 9, inclusive, in which 14 designates a blocksupported on the upper side of the table T, said block being providedwith apertures 14', adapted to receive racks, such as 15 15', the upperends of which are reduced, as at 16 16', to support a platen 17.Centrally journaled in the block 14 and between said racks l5 15' is ashaft 18, having a worm-gear 19 fixed `thereon and also carrying a worm20, adapted It will to engage the racks above mentioned. therefore beseen that when the spindle 18 is rotated both racks 15 15 will be eitherraised or lowered simultaneously, and in this manner they will elevateor depress the platen 17, upon which the log rests. The worm-gear 19 isengaged by a worm, as indicated by 21, Fig. 8, mounted upon a spindle22, having a squared portion 23, to which a wrench may be applied forimparting rotary motion to the same, and in order to cause all of theplatens y17 to be adjusted simultaneously I vpreferably provide eachofthe blocks 14 with aprojection 24, having a bearing 25, in whichisjournaled the hub 26 of a bevel-gear 27,' which is in mesh with asimilar bevel-gear 28,

mounted upon the above-mentioned spindle 22 and secured thereto byaset-screw, (see Fig. 7 so that when any one of the spindles IOO 22. isrotated rotary movement will be imn parted to the bevel-gear 27, whichin turn will actuate the shaft 29, to which similar gears are securedfor the purpose of operating the platens of the entire series of restsR, as will be readily understood, said shaft 29 being suitably supportedon the table rl`--as, for instance, by means of bearings 30.

The head-stock H is shown in Figs. 3 and 4- of the drawings and embodiesa plate 3l, supported on suitable guides or ways 32 and 32', securedupon the upper side of the tableframe and on which said plate 3l may beheld-as, for instance, by clamp-serews 33. The head-stock furthercomprises a slide member 34, which is mounted in ways 35 of plate 3l, inwhich ways said slide may be moved laterally of the table and plate 3lby means of a screw 36, in threaded engagement with a nut 37 at theunder side of the slide 34, such screw being rotatively supported in alug 38, projecting from the upper side of the plate 3l, and having acollar 39 and hand- Wheei 40, by the hub of which and said collar 39said screw 36 is prevented from longitudinal movement in said lug 38.When hand-wheel 40 is rotated, the slide 34 is moved laterally of thetable to increase or decrease the distance between a center or spindle4l, carried in such slide, and the face of the saw S. This spindle 4lconstitutes a centering device for one end of the log to be sawcd andmay be provided with a disk 42, having a series of pins 43, which whenthe work is centered on said spindle 41 will enter the end of the logand cause the same to turn with said spindle when the latter is rotated,while, on the other hand, the pins 43 also constitute means forpreventing the rotation of the log when spindle 4l is at rest.

Secured to the outer end of spindle 4l is a worm-gear 45, in engagementwith a worm 4G, mounted on a suitable spindle 47, which has a squaredend 48, adapted to receive a wrench for imparting rotary movementthereto, and which movement will result in rotating said spindle 41, thedisk 42, and pins 43. The spindle 4l is preferably mounted in a block49, which may be vertically adjusted by a screw 50, said block beingprovided with ears 51, serving as bearings for the above-mentionedspindle 47, so that when said block 49 is adjusted the worm 46 and otherparts carried by the block will be bodily moved therewith.

When it is remembered that the saw S is mounted in a fixed frame andthat the line of travel of table T is at a predetermined distance fromsaid saw,it will be seen that when the slide 34- is moved laterally tothe table in a rearward direction the distance between the axis of thecenter-spindle -tl and the. face of the saw will be increased and thatconsequently the thickness of the slab removed from the log or otherwork may be controlled as desired, and in order to aid the operator insetting the slide 34 to produce a log of the desired size at that end anindex 52 is provided on said slide, the points of which may be made toregister with a zero-mark 53 on the bed-plate 3l.

Referring to Figs. 5 and 6, in which the tail-stock I is illustrated indetail, it will be seen that the construction of the latteris verysimilar to that of the head-stock H and that it embodies a bed-plate 54,movable longitudinally on ways 55and 55 of table T and has mountedthereon a slide 56, to which a reciprocatory motion laterally of thetable may be imparted by means of a screw 57, provided with a collar 5Sand a hand-wheel 59, said screw being journaled in a lug 60, which willserve to preventlongitudinal movement of the screw 57 while it is inthreaded engagement with a nut 6l,provided on the under side of theslide 56. Adjustably mounted on this slide 56 is a post 62, which may besecured to said slide by bolts 63, adapted to enter a series ofscrew-threaded apertures 64, and the foot portion 62 of said post 62 isprovided with slots 65 to permit a limited adjustment of said postrelative to the slide 56. An index 67 is provided on the slide 56 andregisters with the zero-mark GS on thc bed-plate 54, serving as a meansforadjusting the slide 56 to correspond with the position of the slide34 of the head-stock.

In Figs. 5 and 6 of the drawings the post 62 is shown provided with anindex 69, to bc read in conjunction with the zero-mark on the slide 56for the purpose of determining the line of taper or cnt in a log, aswill hereinafter appear. The post G2 is provided with vertical guides7l, which engage a block 72, carryingacenterspindle 73,inscrew-threadedengagement therewith and adapted to be adjusted longitudinally therein,while a checknut 74 may serve to retain said center-spindle 73 inadjusted position.

It should be noted that when the indexes 67 and 52 on the slides 56 and34, respectively, correspond and when the zero-marks 69 and 70 are inalinement the axes of the spindles 73 and 41 are in alinement with eachother and in parallelism with the movement of the table, and hence itwill be understood that when the post 62 is shifted on the slide 56 andtoward the saw the distance between the center line of the spindle 73and the side of the saw'S will be decreased and that therefore the logwill be cut on a taper, since the distance from the center line of thespindle 4l is greater than the distance between the center line of thetail-stock spindle 73 and the face of said saw.

The block 72 may be vertically adjusted on the ways 7l, above mentioned,by means of a screw 75, in threaded engagement therewith, the verticaladjustments of said blocks 72 and 49 being provided to permit the logafter it has once been cut by the saw and its cut face brought lowcrmostto rest on all of the rests R during the succeeding cutting operations.ASaid restsRR serve as steady-rests to sustain the log or other work andprevent the same from sagging, and while said rests are preferably shownas simultaneously adjustable, yet each may have an independent IIOadjustment without departing from my invention, and this could readilybe 'aecomplished in the construction shown by loosening the restrainingset-screw of the particular gear 28 and then adjusting the restindependently to tit an inequality in the work by applying a Wrench tothe squared portion 23 and subsequently turning the spindle in properdirection. v

It is distinctly to be understood that an kind of saw suitable for thepurpose may be employed and that the invention is not limited to thecircular saw shown and described.
